A plicants fil'd Aiigii st e, 1922.

To all whom it may) concern:

Be it known that I, W'I'L'LIAM O. COLEMAN, a citizen'of the United States, residing at Wichita, in the county of Sedgwiclcand State of Kansas, have invented certa-innew and useful Improvements in Heaters; and I'do "declarethe followi'ngto be a full," clear, and exact description of the invention, such as will enable others skilledin the art to which it appertainstomakeand use the same, reference being'had to the accompanyingdra'wings, and to the figures of reference marked'thereon, which form a part of this specification.

This invention relates to liquid hydrocarbon fuel consuming heaters, and the primary object is to provide an efficient,- port able heater, in which the maximum heat may be generated from a given amount of fuel; for example, gasoline. In carrying out my invention, I contemplate the utilization of radiants as part of the burner. The ra'diants, which consist of refractory material, having projections adapted to be heated to incandescence are commercial products previously incorporated as parts of gas stoves. I have'f'ound that these same radiants are similarly adapted foru'se in connection with oil stoves, and by reason of the fact that the projections on the"radiants can be heated to incandescence the gases gen= erated from the gasoline can be misedw a'very high temperature so that practically perfect combustion takes place, the results being that there will be nosoot or smoke present. In this way,.the use of radiants differs from the use of radiants where gas is burned, because the temperature at which the gas is burned has no effect onits com bustible qualities, but if the oilvapors are raised to a very high tempeature, more perfect combustion takes placethan if they are burned at a lower temperature. In other words, the radiants act as 's'uperheaters with very marked results over the ordinary gas,

burner, the effectbeing that the heat generated is very much higher than with the ordinary gas stove. The radiants are preferably arranged in a circle so that the heat may be throughout in radial lines about a common center, but, if desired, parts of the series may be omitted, as, for example, where it is desirable to set the stove in the corner of the room or in front of some object which might be affected by the heat from the radiants. Ordinarily, however,

Ip'refer to arrange the ra'diant's in 'a circle, to obtain the most desirable results.

'The conf'struction of the invention will be understood by reference to the following description, in connection witlrth'e'nccompanying drawings, inwhichfi Fig. 1 is a'persp'ective' view of a heater constructed in accordance with my invention;

Fig.2 is a vertical, longitudinal, sectional View through the same;

Fig 6 is a sectional View tliroughthe radiant carrier, showing the'radiants in sectioni and v 7 is a detailed view of a hot plate which may be substituted. on the base for the radiant carrier. I

Referring now to the drawings by 1111- me'rals of reference:

1 designates a foun't, which also comprises the base of the stove. The fount maybe filled through a filler opening normally closed by a filler cap, 2. The fuel; for ex'' ample, gasoline, is fed to the heater under pressure, and for this purpose I provide a pressure generating pump, 3, in the fount, l, which is provided with apiston rod, 4, con trolledfrom the outside of the fount, as will be clearly seen by reference to Figs. 1 and 2. The pumpdischarges through'the discharge chamber, 5, adapted to be controlled by a' valve, 6, so that when the pump is not in'operation,- conmiunication between the pump and the fount can be cut off by the valve 6. Consequently danger that the pressure will reduce to atmosphere back through the pump will be avoided. Theluel under pressure will be fed to the burner, 7', through a pipe, .8,"which is submerged in the fuel "in the fount, 1, the base pipe 8 connnu'nicating' with the pipe, 9', controlled by the valve, 10. The pipe 9 discharges into the preheater tube, 11, controlled by a val\'*'e', 12. Thep'reheater tube, 11, discharges through a noz zle, '13, into the burner chamber or space, 14'. The burner chamber is circular, and its top is provided with burner tips or discs, 15, through which the gasified fuel may pass. The burner chamber discharges into a tube, 16, immediately below the vaporizing tube, 11, so that the vaporizing tube may beheated to convert the liquid fuel into vapor before it passes to the burner This will be Well understood, as generically it follows the lines of common burner construction. The

burner, 7 is supportedupon the fount by an open collar, 17, which is fastened to the fount by a bolt, 18. The burner is provided with a shell, 19, having spaced perforations, 20, and spaced notches, 21, the latter being in the upper edge of the shell. A radiant carrier is adapted to be supported by the shell, and it may be secured thereto by certain large bars, the radiant carrier, con'iprising a cage consisting of a lower ring, 22, and a top ring,

23, the top ring carrying a canopy or covering 24. The rings .22 and 23 are fastened together'by vertical rods, 25, the rods having depending lingers, 26, with offset portions, 27, terminating in upturned hooks, 28. The radiant carrier may, therefore be fastened to the base by springing in the fingers, 26, so that the hooks, 28, will engage in the v rectangular openings, 20., The movement of the carrier will cause the shoulders, 29, of the offset portions to spring over the edges, 30, of the notches, 21, so that the radiant carrier is held in place. The ring, 22, supports a screen or guard, 31, and within the guard are a plurality of vertical radiants,

32. These consist of upstanding bars of rehave their upper ends extending through a ring plate, 33, which is fastened to the'horizontal wall, 34, of the cowl, 24, by a bolt, 35, between the ring parts 22 and 33; and within the cylindrically arranged radiants is an insulating wall, 86, which is secured to the plates by the bolts 37 (see Fig. 2). The va-' porizing chamber can be initially preheated by placing liquid in the preheater cup, 38, adjacent to the vaporizing tube, 11, and if the tube 11 is heated hot enough to vaporize the fuel, it will furnish gas or vapor to the burner member, 16, so that thereafter the burner member 16 will provide the necessary heat for the vaporization.

The device can be rendered readily portable by fastening a bail, 39 to opposite bars,

25, as will be clearly seen by reference to Figs. 1, 2, and 4. If it is desired to use the heater as a stove, the radiant carrier, or top, may be removed, and a hot plate, 40, may be substituted, the hot plate having depending fingers, 41, corresponding to fingers, 26, Which may be secured in'the openings 20 and the notches, 21. I 1 7 When the parts are properly assembled, it will be necessary only toheat: the vaporizing tube, 11, so that the fuel, which has previously been put under pressure by the pump, will pass through the vaporizing tube, Where it will be converted into vapor in a manner common to oil burning practice. The vaporized fuel will then pass up through the radiants and heat them, as previously described, the radiantsrefractingthe heat in radial lines about the heater.

The vaporizing tube is mounted on. the mixing chamber and swiveled to swing enough to align over the priming pan for preheating, the swivel connection being shown at 42. After the vaporizing tube'is heated so that the oil will be vaporized, the tube can be swung back to theproper position with respect to the burner.

What I claim and desire to secure by Letters-Patent is:

1. An oil stove comprising a. fount, a

vaporizing means abovethe fount communieating therewith, a removable radiant carrier comprising a cage having depending lingers removably engaging the fount, and radiants arranged in a circle Within the carrier abovethe vaporizing means. 2. In an oil stove comprising a fount, a burner carried by the fount, a ring supported above the burner having a radiant receiving groove, a vertical insulating tubecarried by the ring, radiants receivable in the groove in a circle about the tube, a ring at the upper end of the tube having openings therein for receiving the upper end'of the radiants and means for fastening the rings together to hold the radiants in position.

3. In an oil stove having a base, a. burner supported by the base, a plate carried by the base above the burner having an opening therein, a vertical tube in line with the opening to form a flue, a ring at the upper end of the tube, and radiants receivable between the plate andthe ring and arranged in a *circle about the tube.

In testimony whereof I afii'x my signature,

WILLIAM o. oonnM-an.
